Intel Core i7
Hard Drive Recovery - Intel Core i7
Intel Core i7 is a family of Intel desktop x86-64 processors. Launched on November 17, 2008, Core i7 processors were the successor of Intel Core 2 family and also the first processors to use Intel Nehalem microarchitecture. The three current models and two upcoming models are quad-core processors.
Core i7 differs from the Core 2 in several aspects. Core i7 is a single-die device with all four cores, the memory controller, and all cache on a single die. The memory is directly connected to the processor. It Includes 32 KB L1 instruction and 32 KB L1 data cache per core, 256 KB L2 cache (combined instruction and data) per core, and 8 MB L3 (combined instruction and data) “inclusive”, shared by all cores.
Other Important features of Core i7 are the following
- Three-channel memory, each channel can support one or two DDR3.
A new LGA 1366 socket (not compatible with earlier processors) - The front side bus has been replaced by the Intel QuickPath Interconnect interface.
- Motherboards must use a chipset that supports QuickPath.
- Turbo Boost technology allows all active cores to intelligently clock themselves up in steps of 133 MHz over the design clock rate.
- Re-implemented Hyper-threading.
- Only one QuickPath interface, which is not intended for multi-processor motherboards.
- Sophisticated power management can place an unused core in a zero-power mode.
- Support for SSE4.2 and SSE4.1 instruction sets.
One of the drawbacks of Core i7 is that it does not support error-correcting memory.
